Email time zone indicator: +1000

An email sent from someone in the Kilo Time Zone (K) time zone will have the time zone listed as "+1000" in the headers of the email. (However, "+1000" does not have to be in Kilo Time Zone, as other time zones could have the same UTC offset).

Where and when is K observed?

Kilo Time Zone is often used in aviation and the military as another name for UTC +10:00. Kilo Time Zone is also commonly used at sea between longitudes 142.5° East and 157.5° East.

The letter K may be used as a suffix to denote a time being in the Kilo Time Zone, such as 08:00K or 0800K. This is spoken as "zero eight hundred Kilo".
